Application filed. fiecember 6, 1939. Serial No. 531,502.

To all whom it may concern Be it known that l, Josnrn 1V. Sins, a citizen of the United States, residing at East Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Rotary Meters, fully described and represented in the fol lowing specification and the accompanying drawings, forming a part of the same.

This invention relates to liquid meters of that class known as turbine meters in which the liquid acts to rotate a vane wheel, the especial objects of the invention being to provide an improved construction by which the accurate and convenient assembling of the parts is secured, and to provide an improved step bearing for the meter shaft.

In the accompanying drawings, forming a part of this specification, there is shown a construction embodying the invention in a preferred. form and this construction will now be described and the features forming the invention then specifically pointed out in the claims.

In the drawings :Figure 1 is a vertical section of the device on the line 1 of Fig. 2. 2 is a horizontal section on the line 2 of Fig.1. 3 is a detail section of the step bearing,

Referring to the drawings, A is the meter casing, B the inlet, C the outlet, and D the meter wheel surrounded by the central delivery volute E terminating in outlet 0. The liquid passes to the wheel from casing is. through inlets 10 above and below the wheel, and to casing A. from inlet 13 above and below the volute E through vertical strainer The meter wheel D is fixed on shaft 11. which operates the counter through registering mechanism of any suitable form. The shaft 11 is mounted in bearings 12 carried by arms 13 on the top and bottom plates G, H which form the opposite walls f the wheel chamber and through which are the central inlet openings 10. These top and bottom plates G, H, with the shaft 11, bearings 12 and arms 13 are united to .torm a s ngle structure as follows1-The plates G, H are secured together by a sleeve open on the side for the free passage of the liquid. in the form shown, the plates G, H are recessed at their outer edges to reccive rings 1, 2 which are united by standards 3 so as to form the connecting sleeve, the liquid passing freely from the wheel l) between posts 3 which are preferably shaped so to interfere with the llow as little possible. The plates G, H, are secured to the rings 1., 2 by screws 4, the whcei D with itsshait l1 first being put in place in one plate and bearing 12, and the other plate and bearing 1.2 then being slipped over the shaft and the plates and connecting sleeve then secured together. The walls of the volute E are cut out-to receive the plates G, H with the wheel D, and the bottom wall of the volute is formed with a shoulder 5 on which rests the bottom ring 2, thus supporting the wheel and wheel chamber. It will be seen that the meter wheel I) with its chamber plates G, ll, shaft 1.1, bearings 12 and arms 13 are thus united into a single strubture by the rings 1, 2 and posts 3, which structure is simply dropped into place in the volute and may be removed without disturbing any of the adjustments, thus assuring the accurate positioning of the parts while giving ready access to the interior of the volute, and pro viding for convenient assembling and dis assembling of the parts. The wheel and its connected parts may be withdrawn from the casing A by removing the top cap which carries the registering mechanism. The meter wheel and its connected parts may be held in place in the volute only by their own weight, but it may be found desirable to hold them down in place, and for this purpose screw held plates 6 or other suitable means may be used.

sleeve 12 is screw threaded on its outer side to receive an adjustable thrust bearing block 14; which is locked in place after adjustment by set screw 15. The Wheel shaft 12 is tapped at its lower end to receive a metal bearing piece 7,the lowerconicalendofwhich rests in a concavcbearing piece 8,thisbearing piece 8 being carried by a screw block 16 screwed into the end of the thrust bearing piece 14, the bearing piece 8 thus being adjustable vertically and the block l6 being locked in its adjusted position by lock nut 9. The bearing pieces 7, 8 are ot dltlerent metals or suitable material, the piece 7 or its bearing point preferably being of phos phor bronze or Monel metal, and the hearing piece 8 of sapphire. This construction provides a very ctlicient, durable and convenicnt step bearing for meter shafts, in

essence n volute cheniher having its spiral locus in a substantially horizontal-plane, and having its upper and lower walls provided with centrel openings, the lower wall having a, fiangeol'edlge around its central opening, a casing surrounding thervolute chamber and divided into upper and lower inlet chambers.

' central openings in the walls of the volute chamber, thelower side plate resting on the flange of the lower opening, rings fitting in the rabbets of the sicle plates, an l connections between the rings whereb the latter and the plates are securel toget er.

7. lhe combination with the volute' E radial discharge vane wheel- D and wheel shaft 11, of side platesG, H, inclosing the wheel and having inlet openings 10 and carrying shaft bearings 12, ancl rings 1, 2

and connections between them by which the plates G, H are secured-together, said volute E being formed to receive anol support the connected plates.

SQThe combination with the volute E having a seat 5, radial- (lischerge vane wheel l) end wheel shaft 11, of side plates 6%, H inw tnesses.

closin the wheel anti having inlet openings 10 an carrying shaft bearings 12, and rings 1, 2 and connections between them by which the plates G, H are securecl together, said volute E being formed to receive the connected plates and support them on seat 5, and a step bearing for the wheel shaft be- 101w bearing 12 and carried by the bottom p ate.

,9. lhe combination with the volute E radial dischare vane wheel D and wheel shaft 11, of si e plates G, H, inclosin the wheel and having inlet openings 10 an earrying shaft bearings 12, ancl rings 1, 2 and connections between them by which the plates G, H are secured together, said volute E being formed to receive and support the connected plates, and a ste bearing for the wheel shaft consistin o' the e justeble screw thrust bearing in ock 14 on, the end of one of the sleeves 12, the bearing piece '2' inn sorted in the end of the shaft, and the edjustable screw block in the outer ent of block 14 carrying bearing piece 8, said screw thrust bearing block 14: being aimijusteble from the exterior of the wheel structure.
